Bugzilla Bug 98050

Pbbuttonsd 0.7_pre2 is totally dead on my Apple iBook G4, nothing, repeat
nothing works. I had the same problem with 0.6.10.

0.7_pre1 worked partially, excluding only the volume setting. I tried
re-emerging gtkpbbuttons, but that didn't help.

The last version which worked properly was 0.6.9, but because it is removed from
Portage, I can't downgrade to 0.6.9. Have to try 0.6.6, then.

My pbbuttonsd.conf

Can you try 2.6.12-gentoo-r4 instead of 2.6.11?  There are known issues with
2.6.11.  If this doesn't help, can you please provide your kernel config as well?

Thanks

2.6.12-r4 kernel config

Nope, pbbuttonsd 0.7_pre2 is still totally non-functional, regardless of the
kernel upgrade :( . Anyway, here's my new kernel config file.

Alright, there doesn't seem to be anything wrong with the kernel (at least in
terms of pbbuttonsd).  Can you describe the problem a little more?

Does pbbuttonsd start correctly?
Are there any errors in your kernel log?
Does gtkpbuttonsd start and do you get feedback from it when changing settings?
Do you have other powermanagement devices or clients running (pmu?)
Does the fkey switching still work?  How about the CD eject button?
Is it *every* single bit of functionality that pbbuttonsd proivdes that isn't
working?  Just sleep and sound?
Does using the stable version of pbbutonsd help? (Note that some apps may be
compiled for the new version and may not run).

The more information you can give, the faster we can figure this out.

SOLVED!

It didn't occur to me to examine the logs earlier, because the pbbuttonsd seemed
always to start without errors, but the logs eventually gave me the clue about
what's wrong! Here's a log created by 0.6.6:

Jul 10 13:37:18 [pbbuttonsd] WARNING: No event devices available. Lets see
what's wrong._
Jul 10 13:37:18 [pbbuttonsd] - Kernel module evdev.o successfully loaded, that's
it._
Jul 10 13:37:18 [pbbuttonsd] INFO: saving of config enabled to
/etc/pbbuttonsd.conf._

performance ac ' launched and exited normally_

And here's the log after I upgraded to 0.7_pre2 and rebooted:

Jul 10 13:45:37 [pbbuttonsd] WARNING: No event devices available. Please check
your configuration._
Jul 10 13:45:37 [pbbuttonsd] INFO: Soundsystem requested: ALSA and at least

PB Titanium (PMU version: 12)_

performance ac ' launched and exited normally_

I started experimenting with the evdev module the 0.6.6 was complaining about.
'modprobe evdev' didn't work, keyboard and pbbuttonsd still refused to
communicate with each other. Then I added the evdev module to
/etc/modules.autoload.d/kernel-2.6, ran 'modules-update' and rebooted... and
after starting X the pbbuttonsd 0.7_pre2 worked like dream :)

Conclusion: the evdev module needs to be loaded before pbbuttonsd is started. It
seems to me that the 0.6.9 and earlier versions loaded the module automatically,
but the newer versions does not? 

I added a check to the latest pbbuttonsd ebuild that dies if the input event
module isn't built in or a module and warns to load the module if it isn't built in.

Thanks for the report!
